Mazda Rotary Engine

Essentially a portable hand grenade. The apex seals are like pins of a hand grenade attached to a Schrödinger's cat resulting in an engine that it is in 2 states of reality; both working and exploded at the same time.

- Man, did you heard about the RX-9 rumors saying it will come with a mazda rotary engine?
- Yeah, can't wait until it blows up at the mall!

rottainculo

Rottainculo is an italian word that means you have been butt fucked so many times that you have a broken ass hole. So when they tell you you are a rottainculo or rotta in culo, it will mean you have a broken ass hole.

"Sei proprio un frocio rottoinculo" (you are a fag with a broken ass hole)

"Quella puttana si è scopata mezza scuola"
"È proprio una rottainculo" ("that whore fucked half school" "she is such a bitch with a broken ass hole")

rotate his stock

Masturbating to ejaculation, supposedly for the purpose of disposing of old sperm so that fresh, new sperm can take its place.
